As glucose is broken down, some energy is captured by substrate-level phosphorylation, some energy is captured by the reduction of NAD+, but most of the energy is still in the end product, Pyruvate.
Nadh and ATP
ATP molecules.
Energy is measured in calories. 2 ATP gives a gain of 14 kcal. The glucose in glycolysis that grants these ATP is worth 686 kcal. Therefore, only about 2 percent of the energy is released.
Glycolysis is the conversion of glucose into ATP (Adenosine Triphospate) molecules in short. In any case, energy is released.
80%
Initially, the energy to break down glucose during glycolysis is provided by the hydrolysis of ATP to ADP and inorganic phosphate. This reaction releases energy that drives the early steps of glycolysis.
produced and consumed
nadh!
There are a few energy carrier produced during Glycolysis but NADH and ATP are most produced.

during the first step of glycolysis C6 is phosphorylated, turning it into a phosphate ester which is a low energy compound.
So that energy can be released! Wooh yeah!
Glycolysis and the Krebs cycle capture only a portion of the energy in a glucose molecule in the form of ATP. The majority of the energy is released as heat during these processes, and some is used in other metabolic pathways like biosynthesis and maintenance of cell function.
